United States Patent Int. Cl. A61k 9/12 US. Cl. 8-10.2 8 Claims ABSTRACT OF THE DISCLOSURE A composition for dyeing keratinous fibers comprises an aqueous solution of at least one quinoneimine and an aqueous solution of at least one coupler.

This invention relates to a process and composition for dyeing keratinous fibers, particularly human hair. More specifically, this invention relates to dyeing human hair with a dyeing composition containing a quinone imine and a coupler.

Heretofore, keratinous fibers and, in particular, human hair, have been dyed by employing oxidation dyes. In such a process, compounds commonly referred to as bases have been employed. These bases are, properly speaking, not dyes, but under certain conditions they are capable of dyeing the hair as the result of an oxidation process. These bases are essentially aromatic orthoor paradiamines, orthoor paraaminophenols, or their derivatives.

The oxidation of these compounds usually takes place at the moment of their application to the fibers to be dyed by the addition thereto of an oxidizing agent such as hydrogen peroxide.

It has also been proposed, in order to vary the shade of dyeing obtained by this process, to add to these bases, dye modifiers or couplers. The couplers generally used are aromatic metadiamines, metaaminophenols, or metadiphenols, or their derivatives.

Such a process consists in adding at the moment of use an oxidizing agent such as hydrogen peroxide to a mixture of the base and the coupler. This process, however, is rather delicate and the attainment of reproducible shades is often very speculative.

The applicants have now found that it is possible to obtain in a simple way easily reproducible shades, if, in combination with a conventional coupler, a quinoneimine is employed, rather than the conventionally employed base material.

It is therefore a principal object of the present invention to provide a novel composition and process for dyeing keratinous fibers, in particular human hair, which comprises applying to the hair, simultaneously or successively, a solution of at least one coupler and, a solution of at least one quinoneimine derived from a conventional oxidation base. The molar ratio of couplerto quinoneimine employed is generally greater than or equal to 1.

Couplers used in the process according to this invention can be any of those couplers known in the prior art. Thus, it is possible to use an aromatic metadiamine, a metaaminophenol, a metadiphenol, or their derivatives, as well as an arylpyrazolone or a pyridine derivative. Representative couplers useful in the practice of the present invention include resorcinol,

2,6-diarninop-yridine,

6-methyl-3- (N-carbamylmethyl amino phenol, 2-carbamylmethylamino-4-hydroxy-toluene, 1-phenyl-3-methyl-5-pyrazolone,

3,730,677 Patented May 1, 1973 ICC 2,5-dimethylphenol,

! Z-methyI-S-acetamino phenol,

7-hydroxy-phenomorpholine, 2,4-diaminoanisole and 2,6-dimethyl-3-amino phenol.

The quinoneimines used in the process according to this invention are quinone monoor diimines derived from conventional oxidation bases, i.e., compounds whose molecule comprises an aromatic or heterocyclic nucleus alternatively substituted by (1) two amino groups or (2) an amino group and a hydroxyl group which are.

located in ortho or para position relative to one another. These oxidation bases can be aromatic orthoor paradiamlnes or orthoor paraaminophenols or their derivatives, both functional and with substitution, such as those described, for example, in US. Pat. 3,506,389 and incorporated herein by reference.

As disclosed in US. Pat. No. 3,506,389, the oxidation base can have the formula NHz wherein R is selected from the group consisting of hydrogen and lower alkyl having 1-3 carbon, atoms and X is selected from the group consisting of (1) wherein R is lower alkyl having 1-3 carbon atoms and R is selected from the group consisting of -CH CONH CH COOH, --CH CH NHSO CH and and the other entitled, Process for Preparing Indophenols and Their Use in Dyes for Coloring Keratin Fibers, S.N. 49,905, filed June 25, 1970, now abandoned, both being incorporated herein by reference.

A typical example of the procedure involved in oxidizing the base to a quinoneimine comprises heating the base at a temperature ranging between 30 and C. in an anhydrous solvent such as ethyl ether or isopropyl ether and in the presence of an oxidizing agent such as those listed above. Generally, the oxidizing agent is present in amounts ranging between 1 to 2 times the stoichiometric quantity for oxidizing the base, and preferably. 1.5 times this stoichiometric quantity.

The resulting quinoneimine obtained in said reaction can be isolated from the reaction mass by any convenient separation technique, such as by filtration. Thereafter,

the filtrate containing the quinoneimine can be evaporated ciently stable are used in isolated form. Conveniently, these quinoneimines are in the'form of a powder which is put into an aqueous solution at the time of use. These quinoneimines are applied to the fibers to be dyed in the said solution which has generally a neutral pH. With such a solution no extraneous oxidizing agent is required.

As a first variant of this embodiment of the present invention, an aqueous solution of at least one coupler is applied in a first stage operation to the fibers to be dyed. This coupler-containing solution is left in contact with the hair for to 20 minutes. Thereafter, there is applied, in a second stage operation, preferably after rinsing the fibers, an aqueous solution of at least one quinoneimine, which is left in contact with the fibers for about 5 to 30 minutes.

As a second variant of this first embodiment of the present invention, a solution of at least one coupler is mixed with a solution of at least one quinoneimine just before application to the hair, and the fibers to be dyed are impregnated with this mixture which is left in contact with the hair for 5 to 30 minutes.

A principal advantage of this first embodiment of the process of this invention resides in the fact that it is possible to perform the dyeing operation at a neutral pH and in the absence of an extraneous oxidizing agent such as hydrogen peroxide. Such a process is highly desirable, especially in the case of porous hairs which poorly support an alkaline treatment and the action of hydrogen peroxide, or in the situation when it is desirable to avoid a possible allergy reaction to hydrogen peroxide on the part of the person whose hair is being dyed.

It is obvious, however, thatin a case where it is desired to perform, at the same time as the dyeing, an underlying bleaching operation of the fibers, an oxidizing agent such as hydrogen peroxide can be incorporated into the aqueous solution of the coupler or quinoneimine or their mixtures. An alkaline agent such as ammonia can also be added, if desired, to the solution containing the coupler to improve, for instance, the solubility of the coupler in said solution.

In a second embodiment of the process of this invention, especially in those instances where the quinoneimine employed is not sufficiently stable to permit its isolation, the quinoneimine can be formed at the time of its application to the hair, by oxidizing an aqueous solution of a corresponding oxidation base with an oxidizing agent which effects the oxidation rapidly. Generally, the oxidizing agent, which is employed in a molar excess relative to the base, can be, for example, potassium persulfate or ferricyanide. The oxidation is performed in accordance with conventional techniques such as in an alkaline medium having a pH ranging generally from about to '12, at ambient temperature and pressure. The aqueous solution can be made alkaline preferably by adding thereto suflicient amounts of ammonia to achieve the desired pH.

In this second embodiment of the process of the present invention, the coupler containing aqueous solution is applied, in a first stage, to the fibers to be dyed and left in contact therewith for about 5 to 20 minutes. The fibers are then rinsed and, thereafter, in a second stage, the quinoneimine containing aqueous solution, which is prepared just immediately before its application to the hair, is applied to the hair. The quinoneimine containing solution is permitted to remain in contact with the hair for a period of about 5-30 minutes, after which the hair is rinsed and, if desired, shampooed. In this fashion, the desired color is imparted to the hair.

In the dyeing composition of the present invention, the ratio between the molar concentration of quinoneimine and that of the coupler can vary within rather Wide limits, although preferably a molar excess of coupler is employed.

The pH of the two solutions forming the composition of this invention can be neutral or alkaline and is, prefstably, tween. ab ut 7-10.

The composition according to this invention can obviously contain such conventional additives as wetting agents, dispersing agents, swelling agents, penetrating agents or other ingredients usually employed in hair dyeing compositions. Additionally, dyes conventionally employed to color keratinous fibers, for example, azo or anthraquinone dyes, can also be used.

The dye composition of this invention can be in the form of aqueous solutions or in the form of a cream or gel.
